Michael J Mangum, this is a big job and would be best if you had a manual on hand with step by step instructions on your particular year, make, model and engine. You can do a google search for a reasonably priced manual or any auto parts store or visit the local library and borrow theirs. I did search for a freeby for you with no luck. Link below will give you an idea of what is involved in changing the head gasket. Good luck.

I hope this helped you out, if so let me know by pressing the helpful button.
